Skin metastasis of adenocarcinoma of the urinary bladder

A papillomatous tumor developed on the skin from the inguinal region to the middle of the right thigh. The histological findings showed tumor cells with papillary formation surrounded with fibrous stroma, and a diagnosis of metastatic adenocarcinoma of the lower gastrointestinal tract was ascertained. Autopsy findings revealed that the cutaneous metastasis was of urinary bladder origin. This paper reports the extreme rarity of metastasis from adenocarcinoma of the urinary bladder to the skin and the peculiar appearance of the cutaneous metastatic lesion.
